ROTARY YARN-DYEING MACHINE.

SPECIFICATION forming part of Letters Patent No. 581,801, dated May 4, 1897.

Application filed April 4, 1896. Serial No. 586,224. (No model.)

To all 'IU/LG/IL it may concern:

Be it known that I, THOMAS WoLs'rEN- HOLME, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Rotary Yarn-Dyeing Machines, of which the following is a specilication.

My invention relates to rotary yarn-dyeing machines; and it consists of the improvements which are fully set forth in the following specification and claims and are shown in the accompanying drawings.

My invention relates particularly to that class of apparatus in which skeins of yarn are carried upon a rotary reel partially submerged in the liquor.

It is one of the objects of my invention to produce a uniform dyeing of the yarn in a machine of this kind without employing devices for turning the supporting bars or sticks to shift the position of the skeins.

It is also an object of my invention to so support the skeins that the threads will be held open and loose, so that the dye liquor may more readily permeate the fibers.

lVhile my invention is adapted for all classes of yarn-dyeing, it is particularly suited for alizarin dyeing, in which, by reason of the nature of the process, looseness of the yarn is especially required in order that the dye liquor may easily permeate the fibers.

My invention is also especially adapted for dyeing slubbing, because the loose sup porting of the yarn prevents the matting of the fibers, which is liable to occur in all machines where the yarn is held tightly and is shifted on the supporting-sticks by mechanical means.

My invention also relates to improvements whereby the construction is simplified and the adjustment of the yarn-supportin g sticks to suit the sizes of the skeins may be accomplished with facility.

In the drawings, Figure l is a transverse vertical sectional view of a rotary yarn-dyeing machine embodying my invention, taken on the line .r a: of Fig. 6. Fig. 2 is a similar view, on a smaller scale, illustrating a modification of the devices for adjusting the inner yarnsticks. Fig. 3 is a vertical sectional view of part of the yarn-frame, illustrating a further modification of the devices for adjusting the inner yarn-sticks. Fig. 4 is an inverted plan view of an end of one of the upper yarn-supports. Fig. 5 is a transverse vertical sectional view of the same on the line 1 y of Fig. 4. Fig. 6 is a longitudinal vertical sectional view of the machine on the line .2 .2 of Fig. 1. Figs. 7, 8, and 9 are detail views of the connections of the upper yarn-sticks, and Figs. 10 and 11 are detail views of the connections of the lower yarlrsticks.

A is the dye-vat, which may be of convenient shape and construction.

B is the reel-shaft, which carries the reel C and is journaled in suitable brackets Z), carried by the vat A. The shaft B may be driven by any suitable means, as by the pulley B.

The reel 0 is mounted fast on the shaft B and is composed of a series of radial arms D, carrying inner and outer yarn-sticks,by which the skeins X are supported.

The radial arms D are secured to a hub centrally located on the shaft B, so that the arms project radially from the shaft.

In my preferred construction the radial arms are each composed of a pair of Wooden pieces (I (Z, separated a slight distance apart to leave a space for the rod which adjusts the lower yarn-stick. The inner ends of the pieces (I (Z are fastened to the central hub. I prefer to construct the hub, as shown in Fig. 6, of

. an inner central metallic disk. E and two outer disks F, between which the ends of the pieces (I d are clamped and to which they are bolted by suitable bolts f. Metallic washers 6 may be located between the central disk E and the pieces (Z d. The outer ends of each pair of pieces (I d are secured to a small metallic frame G, which is provided on each end with projecting arms G G, to which are secured- ICO . bottom of the stick.

the bar I is secured. The plate .I is thus free to move up and down on the arm D for the purpose of adjusting the position of the bar I.

To move the plate J, I employ a threaded rod K, the inner end of which is journaled in a socket 7c in the periphery of the central metallic disk E and the upper end of which is journaled in the frame G on the upper end of the radial arm. This rod K passes through an internally-threaded sleeve j in the plate J, and it is apparent that by turning the threaded rod K the plate J and bar Iwill be moved in or out.

I have shown the upper end of the rod K extending through an opening in the plate G and provided with a bearing-flange d between the face of the plate G and a top cap L, secured to the plate. The rod K terminates in a non-circular extremity Z, projecting through the cap L, to which a key may be applied to turn the rod and adjust the bar or stick I.

It will be observed that the reel is composed of a series of central radial arms, each of which carries a pair of outer centrally-supported longitudinal stationary yarn sticks or bars and an inner longitudinal adjustable stick or bar. The skeins are slipped upon the yarn sticks orbars from the free ends and are disposed about the pair of outer sticks H II and the inner stick I, as shown in Fig. 1. The reel is then rotated and the skeins are carried through the liquor and are exposed to the atmosphere in the usual manner.

By employing the three sticks II II and I and supporting the skeins loosely I am able to dispense entirely with all devices for retating the sticks to shift the position of the yarn, as the movement of the reel will impart to the skeins as they travel through the liquor an independent movement, which will cause them to constantly shift and change their position upon the sticks, as indicated by the arrows in Fig. 1.

To prevent the skeins slipping from the open ends of the sticks, I provide the sticks adjacent to their ends with pins 72', which are preferably loose or removable, so that they may be pushed down or removed when the skeins are being placed in the sticks or removed from them. In Figs. 5 and 6 I have shown one of these pins loosely supported in a hole in the end of the stick and held in a raised position by a pivoted plate a on the By moving the plate a away from the hole the pin 77. may be pushed down so as not to obstruct the skein in passing on or off the stick.

To strengthen the reel as an entirety, bracepieces 0 may be arranged between the adjacent arm D or bars II.

In Fig. 3 is shown a modification of the means for adjusting the inner bars I, in which the bar is provided with a yoke 12, engaging the arm D, and a set-screw m, carried by the yoke and engaging the arm D or a rod K thereon, clamps the bar I in adjusted position.

In the modification shown in Fig. 2 I employ devices for adjusting all of the inner bars simultaneously and equally. The inner ends of the threaded rods K are provided with bevel-gearsN vhich engage a rotatable bevelgear 0, loosely mounted on the hub or shaft B. WVhen the bevel-gear O is turned, all of the threaded rods K will be turned correspondingly and the bars I will be moved in or out, exactly as in the construction shown in Figs. 1 and 6. The bevel-gear 0 may be provided with a handle P for turning it.

The various details of construction which have been shown may be varied without departing from the invention.
